How to perform a autosubmit with Vugen (http protocol)

Hi folks,

In my HTTP/ HTML script I am facing a problem to submit an request. The request is autosubmit lanching by a javascript.

During the recording, for submiting my form I pressed ENTER, but any parameterwas recorded...

Dev explained me that there is an autosubmit in the page.

Here is the HTM code :

<href="javascript&colon;__doPostBack('ctl01$SubmitButtonLink','')">OK</a>

I try a web.link function :

web.link(
    {
        stepName : 'OK', 
        text : 'OK', 
     //   snapshot : 't2.inf'
    }
);

But I have this error in return  Invalid scheme (not "http:" / "https:" / "ws:" / "wss:") in "javascript&colon;__doPostBack('ctl01$SubmitButtonLink','')"

My question is there is a way to perform a Javacript action in Vugen. 

thanks for your responses.

Best 

Romain
